- Details on results:
- CLINICAL SIGNS AND MORTALITY: There were no deaths. The dosages were well tolerated, with lethargy being the prominent clinical sign of toxicity.
BODY WEIGHT AND WEIGHT GAIN: The high dose group exhibited statistically significantly lower body weight gains than the saline control group.
GROSS PATHOLOGY: The most common pathologic findings were confined to the kidneys, stomachs, and, to a lesser degree, the livers. Stomach lesions appeared related to the irritant effect of the hydrocarbons on the stomach lining. Such lesions included erythema, erosion of the gastric mucosa, rasied discolored foci on the gastric epithelial lining and ulceration. The severity and incidence of these lesions were generally dose-related.
HISTOPATHOLOGY: NON-NEOPLASTIC: Renal: The test material induced a strong nephrotoxic response at both doses which was characterized by (a) hyaline droplet accumulation in the cytoplasm of epithelial lining cells of the proximal convoluted tubules, (b) degeneration or regeneration of the epithelial cells in the renal cortex, and (c) the development of granular proteinaceous casts in the lumina of tubules located between the inner and outer stripe of the medulla.

Applicant's summary and conclusion
- Conclusions:
- The procedure was designed to investigate hydrocarbon nephropathy. Unleaded gasoline was used as positive control.
- Executive summary:
Four naphtha streams, among fifteen hydrocarbon compounds, were administered to two groups of male Fischer 344 rats by oral gavage at the dose levels of 500 mg/kg/day and 2000 mg/kg/day five days per week for four weeks. The procedure was designed to investigate hydrocarbon nephropathy. Animals in both groups experienced lethargy and significantly lower body weight gain was observed in the animals at the high-dose group. The only histopathological difference found was in the kidneys of all male rats. The kidney effects observed in male rats are indicative of alpha-2u-globulin nephropathy. These kidney effects are specific to male rats and are not considered to be of biological relevance to humans. Unleaded gasoline induced a strong nephrotoxic response.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
